DE102007028009A1 - Container for cargo, has inner and outer cover with sharp edged or rounded corner and edge close areas and outer surfaces, where outer surfaces exhibit concave surfaces beside areas, and concave surfaces are curved in set of directions - Google Patents

Abstract

The container has an inner and an outer cover with sharp edged or convex rounded corner and edge close areas and six outer surfaces. The outer surfaces exhibit a set of concave surfaces beside the corner and edge close areas. The concave surfaces are curved in a set of directions. A wall of the container contains expanded polystyrene, polypropylene, PVC or foam or hard plastics. The wall of the container has outer layer expanded polypropylene, vacuum isolation panels as additional thermal isolation layer and interior layer hard plastic.

Description

Container today are cuboid due in most cases the general built on such cuboid forms logistics. nevertheless are also other container forms known z. B. cylinders or molds, the as base area Multi-cornered, for example octagons use.

Independently of are for many reasons the known container forms for special purposes, but not optimal for transport. So z. B. the corners and edges of the previous container the handling on the transport mechanically much more stressed as the smooth surfaces for example, a cube. At the same time, they are flat, smooth surfaces often disadvantageous for the grip behavior of a container. There are also the corners and Edges, the most thermal energy in thermal transport containers submit.

The solution for the According to the invention, the problems just described lie in one of the claims Shape of the transport box. According to the invention, a container form is proposed in which the outer surfaces are concave are shaped. This will add more material to the corners and edges of the Container brought, thereby reducing the mechanical stress on these Points can be much better intercepted. It is also on These points in thermal transport containers, the outer shell of foam insulation exists, the wall thickness thickened, resulting in a better thermal insulation results. The rounded corners and edges are also at bumps and less sensitive and lead to a more stable unit.

By the dilution the wall becomes particularly in the central areas of the side surfaces first a mechanical or thermal weakening accepted. Indeed have these central areas for the mechanical stability, in particular the impact protection, less importance than, for example, the edges and corners. The first doubtless existing thermal weakening in the central areas can be easily compensated by other measures become. So can for example vacuum insulation panels within the outer shell the reduce the thermal losses of the container so significantly that the low thermal attenuation in the central surface areas practically does not matter anymore.

By then also concave shape along the edges formed a very advantageous grip situation, which makes it possible, for example, at standing box well under the edge and secure To find a handle. Is the box on a carrying handle or a carrying strap worn, then the container shows a good adaptation to the body contours, which leads to an ergonomic wearing comfort.

By special design of the underside of the corners or by a Crosswise stacking can also provide better stackability be achieved. In this case, the concave shape leads to a better distance to a neighboring box with the following advantage in thermal boxes: a thermal interaction between individual Boxing is by the possible Air convection prevented much better than neighboring boxes, the over the entire area touch directly. This can be of considerable advantage if, for example, a box equipped with dry ice and the temperature of the product in the adjacent box is not below 2 degrees Celsius may fall.
